- How does this releate to the rest of GAS ?
-
- Well, all the other files in gas are more or less a black box. It
- takes care of opening files, parsing command lines, stripping blanks
- etc etc. This module gets a chance to register what it wants to do by
- saying that it is interested in various pseduo ops. The other big
- change is write_object_file. This runs through all the data
- structures that gas builds, and outputs the file in the format of our
- choice.
